Embodiment 1

[0071] Embodiments of the present invention will be described from the perspective of a parking lot management system. The parking system may include a card issuing device and an authentication device, wherein the authentication device may include a terminal, a SAM card, and a CPU card.

[0072] A safety authentication method applied to a parking lot, comprising: reading a first root key and a second root key, generating a master control key according to the first root key and the second root key, and secreting the master control key The key is distributed to generate the main card issuing key and the SAM card issuing control key, and the CPU card sub-key is generated according to the card-issuing main card key, and the SAM card key is generated according to the SAM card issuing control key, and the CPU card sub-key is generated according to the SAM card issuing control key. and the SAM card key to authenticate the user identity.

[0073] Such as figure 1 As shown, the specif...

Embodiment 2

[0121] According to the method described in Embodiment 1, an example will be given below for further detailed description.

[0122] Such as Figure 2a As shown, the figure is a schematic diagram of the principle of the parking lot management system, such as Figure 2a As shown, the parking lot management system can include a card issuing device and an authentication device, wherein the authentication device can include a terminal, a CPU card and a SAM card, and in addition, the authentication device can also include a parking lot controller, wherein the structure and function of each device are specific Can be as follows:

[0123] (1) terminal;

[0124] The terminal may include modules such as a micro control unit, a communication module, and a radio frequency interface;

[0125] As the initiator and contactor of the interaction between the SAM card and the CPU card, the terminal transmits and processes the interaction information between the SAM card and the CPU card.

Abstract

The invention discloses a safety authentication method applied to a parking lot as well as a related device and a system. The safety authentication method comprises the following steps: reading a first secret key and a second secret key; generating a general control secret key according to the first secret key and the second secret key; carrying out dispersion calculation on the general control secret key to generate a card dispensing master card secret key and an SAM (Security Account Manager) card dispensing control secret key; generating a CPU (Central Processing Unit) card sub-secrete key according to the card dispensing master card secret key and generating an SAM card secrete key according to the SAM card dispensing control secret key; and identifying the identity of a user according to the CPU card sub-secrete key and the SAM card secrete key. The secret key injection of the scheme has certain order and level and the secrete keys of each layer have a mutual protection dependence relation so that the secrete keys have high safety; according to the scheme, a CPU card and PSAM (Purchase Secure Access Module) card interactive identification manner is adopted for identifying the identity of the user so that the protection to use data is greatly enhanced and the safety of a parking lot management system can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a security authentication method, a related device and a system applied to a parking lot. Background technique [0002] With the rapid development of the economy, the parking lot has become an indispensable part of our daily life. How to better manage and control the parking lot has gradually become a problem that people pay more and more attention to. [0003] At present, most of the parking lot management systems in our country use non-contact integrated circuit (IC, integrated circuit) cards, and all of them use non-contact logical encryption cards. Among them, the non-contact IC card is mainly composed of an IC chip and an induction antenna, which is completely sealed in a standard polyvinyl chloride (PVC, polyvinylchloride) card without exposed parts; the reading and writing process of the non-contact IC card is usually performed by The communication between the...
